Hopefully the STEM aspect of it will give it extra educational value.
On the subject of STEM - I'd find it quite interesting if they did like with the celebrity special but as a longer challenge - taking groups of people who don't have the skills and background, etc. and pairing them up with some of the experienced builders and actually go through designing and building and finally fighting - maybe not with the sophistication of some of the current robots and probably with more off the shelf parts, etc. but still.
